5 Format and interpretation of tests

3GPP51.021Base Station System (BSS) equipment specificationRadio aspectsRelease 17TS

Each test in the following clauses has a standard format:

X Title

All tests are applicable to all equipment within the scope of this specification, unless the title of the test is Applicability (Phase 2) or Applicability (Phase 2+), and the applicability is defined below.

X.1 Test purpose

This subclause defines the purpose of the test.

X.2 Test case

This subclause describes the steps necessary to perform the test. The general test conditions described in clause 4 also apply.

X.3 Void

This subclause is not used any more.

X.4 Conformance requirement

The conformance requirement describes the complete set of tests which may be performed to fully characterize all aspects of one performance parameter of the BSS.

Test environment

This subclause describes the test environment or environments under which the test shall be performed. Where more than one test environment is specified, the extent of testing is specified for each environment.

Minimum requirement

This subclause describes the requirement which shall be met for the specified tests.

X.5 Requirement reference

This subclause gives the reference to the subclauses in the GSM specifications from which the test requirements have been derived. Where the Requirement reference subclause references the ETSs corresponding to both the Phase 2 and Phase 2+ versions of the same GSM specification, the Phase 2 and Phase 2+ requirements which are referenced are consistent. If the test case and/or requirements are different for Phase 2 (ETS) and the various releases of Phase 2+ (3GPP TS), this is stated in the applicability part of the subclause. When no applicability is stated the requirements are consistent and the referenced requirements apply to all referenced specifications (ETS or TS).
